The previously completed Comprehensive Plan provided a broad view of the system and potential
improvements needed. The purpose of this Feasibility Study will be to provide more detailed information
than previously provided. At a minimum, the Feasibility Study should include for each of the four service
areas:
1. Review of the previously completed Study and sanitary sewer model.
2. Confirmation of proposed service area extents and estimate of ultimate average and peak
sanitary flows.
3. Identify potential adjustments in pipe sizes, configurations, and sequencing to serve the service
area due to recent changes in anticipated growth since the 2018 Comprehensive Plan.
4. Provide additional preliminary design information for the proposed primary lift station.
5. Provide additional preliminary design information for the proposed sanitary sewer collection
system upgrades. This should include approximate rim and invert elevations for structures. Pipes
should include size and slopes base on PVC material.
6. Provide additional preliminary design information for the proposed sanitary sewer force main and
connection to the wastewater treatment facility or other downstream facilities.
7. Provide phasing information for these improvements and potential limitations to expansion.
8. Note critical areas where existing ground cover may be a concern. A pipe and ground profile
should be provided.
9. Provide cost estimates for each of the identified improvements as noted above and shown in the
Figure for the Study Area. These costs would be related to the sanitary sewer component only,
and not water main, storm sewer, street construction, or property acquisition. Costs should be
broken down into segments or phases.
10. Provide potential funding sources for how the work may be completed.
For this Proposal, the consultant should assume that improvements as identified in the previous
Comprehensive Plan shall be used with minimal adjustments to piping configurations. The study should
be GIS-based using available county and state-based information for elevations, aerial images,
coordinates, and parcel information. The City shall make available the sanitary sewer model along with
utility information in ESRI formats. It is expected the consultant will provide topographic survey of existing
sanitary sewer connection points as required to determine precise pipe elevations as needed.
In preparation of the Feasibility Study, consultant is expected to meet with City Staff to review the
potential improvements prior to starting work and at regular intervals (minimum monthly) to review
progress and address items within the Study. At completion of the Study, consultant shall present findings
to the City Council. The study shall be provided to the City in electronic format and mapping linework
used within the report provided in ESRI format. Updated sanitary sewer models shall be provided in
InfoSWMMM or comparable formats. Proposal Requirements
